3D Three dimensional figure

Drawing three-dimensional images mainly through mplot3d Module implementation .

from matplotlib import pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
%matplotlib notebook

3D mapping

3D Drawing and 2D The method of drawing is basically the same , The difference is , The object of the operation becomes Axes3D() object .

3D Scatter plot

from matplotlib import pyplot as plt
import numpy as np
from mpl_toolkits.mplot3d import Axes3D
x = np.random.rand(100)
y = np.random.rand(100)
z = np.random.rand(100)
fig = plt.figure()
ax = Axes3D(fig)
ax.scatter(x,y,z,s=10,color="r",marker='o')
plt.show()

3D diagram

from matplotlib import pyplot as plt
import numpy as np
from mpl_toolkits.mplot3d import Axes3D
zline = np.linspace(0,15,1000)
xline = np.sin(zline)
yline = np.cos(zline)
fig = plt.figure()
ax = Axes3D(fig)
ax.plot(xline,yline,zline)
plt.show()

3D plan

x = [1,2,3,4]
y = [1,2,3,4]
X, Y = np.meshgrid(x, y)
# Create a canvas
fig = plt.figure()
# establish 3D Coordinate system
ax = Axes3D(fig)
ax.plot_surface(X,
Y,
Z=X+Y
)
